I believe the tyre pressures marked on the casing are a maximum at a set temperature to be used in the USA and are not applicable here.
As big ape says, tyre pressures are very personal. I think with the modern technology in tyres requires less pressure than older tyre types.
Truck Tyres used to be inflated to 110 psi to carry loads of 32tonne, now they are inflated to 85 psi and carry 44 tonne.
I believe Bike tyres are the same, the carcass has to move to heat up the chemicals in the rubber,
My opinion only, but I think 42 is much too hard for these modern tyres
This post will cause some argument I think :P
